Answer: The fixed amount of energy that a system described by quantum mechanics
Explanation: Quantum mechanics are molecules, atom, electron, or nucleus.
Answer:
It depends on the number of significant figures you are changing to
Explanation:
6.02×1023=6158.46
1 sig fig = 6000
2 sig fig = 6200
3 sig fig = 6160
4 sig fig = 6158
5 sig fig = 6158.5
6 sig fig = 6158.46
When solving significant figures you have to consider the number after each number like in the case of changing to two sig fig the number following one is five and when the number is up to or greater than five you add a value of one to the number before it. But in a case where the number is less than five you just leave it like that like in the case of changing to one sig fig
First find the names of the acids end in “acid”. Acid formulas have one of these forms: HX(aq) or HaXbOc then find the Ionic compounds that contain hydroxide. (OH-) , carbonate (CO32-) , or hydrogen carbonate (HCO3-) anions are basic.
Answer:
a) 231.9 °C
b) 100% Sn
c) 327.5 °C
d) 100% Pb
Explanation:
This is a mixture of two solids with different fusion point:
<u>Given that Sn has a lower fusion temperature it will start to melt first at that temperature. </u>
So the first liquid phase forms at 231.9 °C and because Pb starts melting at a higher temperature, that phase's composition will be 100% Sn.
The mixture will be completely melted when you are a the higher melting temperature of all components (in this case Pb), so it will all in liquid phase at 327.5 °C.
At that temperature all Sn was already in liquid state and, therefore, the last solid's composition will be 100% Pb.
Answer:
36 atoms
Explanation:
- C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy
The reactants are in the left side of the equation. <u>First we determine how many atoms are there in the C₆H₁₂O₆ molecule</u>:
- 6 C atoms + 12 H atoms + 6 O atoms = 24 atoms in total
There are two atoms in a O₂ molecule, and there are 6 O₂ molecules in the equation:
- 2 * (6 O atoms) = 12 atoms in total
The total number of atoms in the reactants is
